CAR-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 402,541, dated April 30, 1889.

I Applioation filed April 1883. Serial No. 271,421. No model.)

To to whom it may concern.-

Be it known that I, JOHN B. PORTER, of New York, county and State of New York, have invented an Improvement in Car-Heating Apparatus, of. which the following description, in connection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts. A

This invention has for its obj ect to'improv the construction of car-heating apparatus,

and it consists in-various details of construction, to be hereinafter pointed out.

In accordance with this invention a heater comprising steam and water chambers is employed, the steam-chambers being filled with steam taken from the main steam-pipe, located beneath the car, and the water-chambers being'in operative contact with the warming or circulation pipes. An auxiliary heater,

:0 preferably what is commonly known as the Baker or Johnson heater, may be eniployed, the heating coil or reservoir of such heater also being in operative contact with the system of warming-pipes.

2 5 Figure 1 shows in vertical section and partial elevation a car-heating apparatus embodying this invention; Fig. 2, a top view of the main heater, to be described.

The auxiliary heater A, containing the heat- 0 ing-coil a, is of any suitable or welhknown construction, the upper end of said coil being connected with the reservoir or expansionchamber a by the pipe to. A pipe, a leads from the said reservoir and connects with the 3 5 system of warming-pipes extended through the car. The lower end of the coil a is also connected to the warming-pipes by the pipe 0.

The main heater consists of two like boxes .01 heads, 1' 11, each of which is cored out to form within a large'chamber. The box L has upon each side a series of openings, herein shown as six in number, the openings upon the upper side corresponding as to position with those upon the under side, but being 5 made somewhat smaller than the openings upon the under side, and the box or chamber 2' has corresponding openings arranged re versely-that is to say, the smaller openings being upon the under side. Several tubes, as

i are placed within tubes i and are connected at each end with the boxes or heads z i, the smaller or inner tubes, t passing through the larger openings in the boxes and being secured to the boxes at or within the smaller openings, while the larger tubes, 1 are secured to the boxes at or within the larger openings. Two other boxes or heads, n n, suitablycored out or formed to present within annular chambers, as n a are secured to the heads '6 11', the chambers within communicatmg by a series of openings, as n, with the smaller or inner pipes. A pipe, m, leads from the chamber a of the head at to the main steam-pipe B beneath the car, and when the three-way cock (2 or other controlling-valve in said main steam-pipe is open the chamber 72 of the head it will be filled with steam, which also fills the pipes 2' and the chamber a of the head or. A pipe, m leads fromthe chamber n of the head at, which pipe serves as an escape-pipe for the water of condensation, such escape being controlled by a cock, m placed in said pipe. A pipe, 0, leads from the chamber f of the head i, which pipe communicates with the pipe a, and a pipe, 0', legflsm from the chamber f of the head vi, wh

communicates with the system of warming pipes. The water contained in the reservoir a fills the chambers f f and the annular space formed between the tubes F11 It will be observed that as the steam is admitted to the chamber a and the inner pipes,

t the water contained in the water-space between the pipes i i will be heated to start and thereafter maintain a continuous oircula- 8 5 tion.

v A pipe, 8, connects the steamchambers n a and a water-gage, w, is attached to said pipe to determine the height or quantity of water of condensation contained in the steamo chambers.

'pipes may be heated by a flame, if desired.

I claim- 1. In a car-heating apparatus, the combination, with the main steam-pipe and a system of warming-pipes, of several vertical waterreservoirs connected to each other at their ends by the chambered heads 1 i, and in communication thereby with the Warming-pipes, that the water may circulate freely there through, and several steam-reservoirs, '5 passing entirely through said chambered heads, in communication with the main steam-pipe and with each other by the chambers 01 n and extended through the said water-reservoirs and surrounded throughout their length by the water contained therein, substantially as described.

2. In a car heating apparatus, the main steam-pipe and Warming-pipes, combined with the Water-chambers ff, connected by two or more pipes, 6 attached to the under and upper side, respectively, of the said chambers, and the steam-chambers n of, secured and adjacent to said chambers f f, respectively, and connected by two or more pipes, 1' arranged Within, parallel and concentric with relation to the water-pipes and passing completely through, but not communicating with, said water chambers, substantially as described.

In a car-heating apparatus, the heater herein described, comprising the chambered heads 2' i, joined by the pipes '6 attached to the under and upper sides, respectively, of the said heads, and the chambered heads 71 n, joined by the pipes i which pass through the chambered heads 11 t" and concentrically through the pipes t, substantiallyas described.

4. In a car-heating apparatus, the heater comprising several vertical water-reservoirs, i completely. inolosed in a drum or casing, 0, open at its ends and adapted to be heated externally by a flame in said drum, combined with the warming-pipes attached to said reservoirs at the end thereof, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN B. PORTER.
